IMPROVEMENT IN RECLINlNG-CHAIRS.

Specification forming part of Lettere Patent No. 190,788, dated May 15,1877; application led September 7, 1876.

To all whom it may concern Be it known that I, HERBERT S. SMITH, ofBrooklyn, in the county of Kings and State of New York, have invented anImprovement in RecliningGhairs, of which the following is aspecification z Chairs have been made with stationary arms, and with aback that is hinged at the rear of the seat, and links extending fromthe back to the arms with notches to go over pins in the arms. A Inthese chairs it has been necessary either to use a pin with a head, soas to prevent the link slipping off, or else to have a two-part arm withthe link between. I avoid the use of either ol' these devices by makingthe notches of an outwardly-daring shape, and the catchpins tocorrespond, so that the links cannot slip ofi' the pins laterally.

In the chairs heretofore made, the links at each side have had to beoperated separately, which is inconvenient, especially with a sickperson. To avoid this I connect the links together at the back, so thatthey can both be lifted when the power is applied to either link.

In the drawing, Figure 1 is a perspective view of the chair-seat, arms,and back. Fig.. 2 is a section of the pin and notched link, and Fig. 3represents the mode in which the ilaring notch of' the link and thediverging pin can be applied in a folding chair.

The side pieces a c' of the back frame are hinged at b b to the seat c,or at any other convenient place iu the reclining-chair, and the arms dd are of any desired character, and the links c e' extend from the backand catch over the pins g. The notches in the links c c are notparallel, but flaring, so as to receive the pins g' Without their endsprojecting necessarily beyond the outer surface of the link, because thetapering or conical form of the pin prevents the link slipping off, andthere is nothing to catch in the clothing, and the appearance of theparts is improved.

The links c c are pivoted to the back frame c c', and also connectedtogether, so that one link cannot be lifted without the other. This ispreferably accomplished by the bar f that extends from one lnk,e, to theother, c', and is firmly attached at its ends. This bar f can be used tooperate both links at one time from the back of the chair, or eitherlink c or e can -be lifted and the other one will be simultaneouslymoved, thus allowing the chair-back to be inclined more or less to suitthe occupant, and in so doing only one hand is required.

I claim as my invention- 1. In a reclining-chair having a hinged back,the combination of the links provided with flaring notches, and thecatch-pins, of a similar shape to the notches, substantially as and forthe purposes set forth.

2. The combination, in a reclining-chair. of a swinging hinged back,notched links, catchpins, and a bar, f, connecting the links, so thatthey move together, substantially as set forth.

HERBERT S. SMITH.
